Auniform conducting rod of length 22 cm has a potential difference across its ends equal to 41 mv (millivolts). what is the magnitude of the electric field inside the conductor in units of n/c?

0.186 N/C

Explanation:

The relationship between electric field strength and potential difference is:

where

E is the electric field strength

is the potential difference

d is the distance

Here we have

d = 22 cm = 0.22 m

So the electric field magnitude is
